Foil backing (or foiling) is a gemstone surface enhancement technique where a thin sheet of metal or other material (sometimes colored) is placed behind the gemstone in order to reflect more light, and/or color, back into the stone and then towards the viewer. A precious example we have here.
A sweet petite rose-cut diamond is found before a simmering foil, bezeled and closed back set in sterling silver, perched atop a crown-like 18kt setting with a well-worn band that warms to the touch.

Please view and inspect any photos closely. We endeavor to fully disclose all condition information clearly and concisely, however, please note that what qualifies as excellent condition for historical jewelry differs from modern and contemporary pieces; please take the age of the piece into account when examining the piece. Minor age wear is typical and to be expected for antique and vintage jewelry. Unless otherwise stated, gemstones have not been officially graded for color, clarity, or treatment by GIA; any information provided is our own educated, professional assessment.
